I have Blanche married to Sir William Stanley c1380 - d 1428 son of Sir William Stanley b c1362 - d Feb 1428. Both died in the same year.
Blanche appears to have been the daughter of Sir John Ardern Kt., 1300 - 1349 who married Ellen Arderne (Wastenys) 1318 - 1349
An extra generation seems to have been inserted here, with Blanche ostensibly the grand-daughter of Sir John and Ellen Arderne and the daughter of Sir Thomas Arderne and Katherine (Stafford) Arderne.
